Security attachment and method for use with a security slot, e.g. in a laptop computer

摘要

A security attachment for engagement in a security slot (1100) in the casing of a laptop computer or the like provides a body (1) with a rotatable lock (10) and a projecting tongue (20) which is axially retractable into a flat sided, rotatable outer casing (2). A pair of spring steel strips (40, 50; 100, 110) are slidably mounted in an elongate cavity (22) in the tongue. The tongue is inserted into the security slot by pushing the lock into the casing, and then locked in place by rotating the lock so as to advance the strips axially through the security slot within the tongue. The distal ends (42, 52; 102, 112) of the strips are deflected progressively outwardly via lateral apertures (23, 24) at the distal end (27) of the tongue by sliding engagement with a wedge (28, 29) formed at the distal end of the tongue so that they engage the laptop casing at the periphery of the aperture at an oblique angle.
